SKATE.

Specification of Letters Patent.

Patented Mar. 23, 192e.

Application filed April 5, 1919. Serial` No. 287,702.

. To all whom t may concern:

Beit known that I, JOSEPH SALOMON NEL- soN GUTNDON, a subject of the King of Great Britain, residing at' Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Skates; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same.

The invention relates to cycle Skates and more particularly pertains to that type of device adapted for attachment to the feet and which are pedually operated.

The primary object of the invention contemplates the provision of means for actuating the propelling mechanism by the downward pressure alternately exerted upon l the Skates and providing for the escapement of the actuating mechanism upon the elevation of the pressure mechanism.

A further object of the invention is to provide means for effectively guiding the skates and automatically controlling the guiding mechanism.

A still further object of the invention is to provide a suitable brake mechanism which is likewise automatically controlled by the engagement of said mechanisms together.

With the abo-ve and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any alterations or modifications to which recourse may be had that come within the scope of the claims without departing from the spirit of the invention or sacrificinc' the efficiency of the same.

Fig. 7 is a detail elevation of the additional escapement mechanism;

Figs. 8 and 9 are modifications of the guiding mechanism; and,

Figs. l()` and 11 are further modifications of the guiding elements positioned at the front of the skates.

Similar letters of reference indicate corresponding parts in the various figures of the drawings.

Referring to the drawings, the numeral 1 designates the skate frame proper, comprising two flat bar members 2, preferably constructed of steel, which are spaced apart for their greater length and are connected by the plates 3. The forward ends of said bar members 2 are bent upwardly at i in an arcuate plane and inwardly toward each other and finally overlap. The said bar members 2 at this point are welded together and apertured for the reception of the forward steering post 5, which latter carries the front fork 6. A wheel 7 tted with the usual rublber tire, is pivotally mounted on a shaft 8 in said fork 6, and is provided with a hub 9. The opposite ends of the flat bar members 2 are bent upwardly at right angles and these bent up portions 10 are spaced apart and apertured for the reception of the hub shaft 11, carrying the rear wheel 12, of similar construction as the front wheel 7.

That portion of the skate frame l, disposed intermediate the bent up portions 10 and the arcuate portions f t, is in axial longitudinal alinement with the wheel shafts 8 and 1l and, therefore, 'has the appearance of being underslung.

The bent up portions 10 of the frame l are spaced apart at the rear of the same and provide bearings for the shaft 13, carrying the pulleys 14 on the opposite extended poirtions thereof and a Segment member 15,

`with the gears 37 tion 39, upon which mounted on the cross bar 16 of the fork 6, has its arcuate edges grooved at 17. A wire cable 18 is secured at its free ends to levers 19, pivotally mounted on the depending brackets 2O at eachside of the frame and the said levers 19 have portions bent at right angles thereto, and the portions 21 are apertured for the stub shafts 22, carrying the two guiding wheels 23. The wire cable 18 as before stated is secured at its free ends, to the upper extremities of levers 19 and is trained overl the grooved pulleys 14 and around the segment member 15, so that, movement to the steering post 5, is tra-nsmitted by the guiding wheels 23, through the above recited associated elements. The springs 24 are secured at one end to the barmembers 2, and normally tensions the upper part of the levers 19, away from the standards 10, and keeps the guiding wheels 23 intermittently out of contact with the road surface. If it is desired to turn to the right the front wheel 7 is turned in that direction by means of the small guiding wheel 23 at the right of the frame while the wheel i3 will be 4out of contact with the road surace.y Y

The steering post 5, forming a continuation of fork 6, extends upwardly some distance from the skate frame and a similar post 25, is secured to a cross bar 26, connecting the bent up portions 10 of the frame, and said posts 5 and 25 have loose collars 27 mounted thereon. Adjustable sleeves 28 are secured to the posts 5 and 25 by the bolts v29 and the outer reduced portions of said sleeves carry the gears 30` and drums 31. Cables 32 are adapted to be wound around the drum sections 33, and the opposite ends of the said cables are connected to said loose 4collars 27, the latter being tensioned upwardly by means of the springs 34 wound varound the drum sections 35. Likewise the large gears 36 are mounted on stub shafts 37 in the fork 6 and the rear frame portions 10. These gears 36 have meshing engagement carried on the shafts 8 and 13, of the front and back wheels 7 and 12, and the latter are driven in the following lmanner Mounted on the main frame, and adapted lfor vertical reciprocatory motion thereof,

is the pedal member 38, comprising an auX- iliary frame having a flat intermediate porthe foot of the operator is adapted to be placed and the latter is se- .eured thereon, by the straps 40, as illustrated.4 Likewise for further securing the skate to the leg of the operator, I provide a post 40 which is secured to the pedal platform and on its upper end carries a strap element by which the post is secured to the leg Vof the operator at a point just below the knee.

This pedal member has connected therewith the arcuate arms 41, the outer ends of which carried by the lever arm 59,

are bifurcated and have pin connections 42 with the collars 27, slidably mounted on the posts 5 and 25.

Motion is imparted to the front and rear wheels 7 and 12, by the chains 43 which are trained over the gears 30 and the pinions 44, mounted on the stub shafts 37. As has been before stated, the large gears 36 on the shafts 37 have engagement with the gears 37 on the wheel shafts 8 and 11.

The bifurcated ends of the pedal member arms 41 have formed integral therewith the extensions 45, which latter are slotted or bifurcatcd and the star pinions 46 are mounted in the bifurcated portions on the shafts 47. These star pinions are normally held in engagement with the chains 43 and the latter are held in such engagement by the rollers 48, having pin connection with the extensions 45, so that, upon the actuation of the pedal member 38, motion is transmitted through the star pinions 4G, to the chains 43 and ultimately to the sprockets 37 on the drive wheel shafts 8 and 11.

By means of the pawl and ratchet mechanisms 49 and 50, (Figs. 3 and 4) the star pinions 46 are only operable in one direction.

It will be understood that the driving mechanism is the same at both ends of the skate and upon downward pressure on the pedal member 38, the star wheels 46 are forced into engagement with the chains 43, actuating the latter over the gears 30 and 44, thereby imparting motion to the large gears 36 and consequently the gears 37 to drive the wheels 7 and 12.

Springs 51 are disposed between the pedal member 3S and the skate frame 1 and the same aid in returning the said pedal member to normal position as illustrated in Fig. 1; also, the spring and drum mechanism illustrated in Fig. 7 serves to draw the pedal member upward to position the star wheels 46 for the downward thrust, to actuate the mechanisms for driving the wheels 7 and 12.

A brake mechanism is embodied in my improved skate and comprises a pulley 52, mounted on the shaft 53, which latter has ball and socket joint connection 54, with one nection 56, with the shaft, through a ball and socket connection 57, and upon the con; tact of the pulley 52, a cable connection 58, is wound upon the said arm to engagement with the shaft 53 and actuates draw the brake belt 60 into the drum 61.

To operate the brakes it is only necessary to press the spring members 55 together, that is, the two skates are brought together,

llO

so that both spring members 55 are in engagement and this action forces the pulleys 52 into engagement with the wheels 7 and 12, to actuate the belt on the drums 61.

The pawl and ratchet mechanism 62 aud 63 illustrated in Fig. 5, controls the operation in one direction of pinion 37.

In Fig. 8, a modification of the guiding means is illustrated, in which the wheels 23 are actuated through the cable 58, which passes over pulleys 64, and the ends are secured to arms 65, pivotally mounted on the frame.

A further modification illustrated in Fig. 9, provides supporting rods 66, which are vertically operable in the cross bar 26 and said rods 66 carry the small guide wheels 23. A rack 67 is formed on said rods and the same are adapted for engagement with the pinions 68, mounted on the shaft 69, in the bent up portion 10 of the frame and the said shaft 69 carries a drum 70 on which is adapted to be wound the cable 58.

In the modification illustrated in Figs.

101l, the guide wheels 23 are carried by a support 71 secured to the front of the frame immediately to the rear of wheel 7, being so arranged, that they pivot on the front steering post 5.

It is obvious, that by the mechanisms set forth, I will have perfect control of the skates and by alternately lifting each skate, and upon pressure downward, the chains will be caused to actuate, to drive the front and rear wheels and in order to ,guide the same it is only necessary to lean in the direction desired and the compensating` mechanism controlling the guiding wheels 23, will automatically steer the skates.

Likewise, the brake mechanism may be actuated by bringing the skates together, so

that the springs 55 are in engagement, which action will cause the tightening of the brake band 60 on the drum 61.

By the use of my invention, a skating device is provided whereby great speed may be attained and control at all times assured.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. An auto-skate comprising a frame having a supporting wheel mounted at each end thereof, a pedal member operable on said` frame, said pedal member adapted to be fastened to the foot of the operator, steering posts mounted in said frame, gears carried by said posts, forks secured to said posts in which said wheels are mounted, gears mounted on said forks, gears secured to said wheels, chain connections between certain of said gears, gears carried by the pedal members for actuating the chains, and a brake on said frame for controlling the movement of said wheels.
